In this study, effects of geometric factors and material properties are investigated on stress behavior of circular rotating disk with constant rotation in various industrial mechanisms using equilibrium equations, geometric relations and stress functions. In this way, research on a thin uniform and homogeneous circular disk under constant rotation is considered. The rotating motion produces centrifugal acceleration on each element of the rotating disk, and this rotating motion becomes the source of external loading for the mentioned problem. Additional exterior loadings are not assumed in this problem. It is comfortable to handle the centrifugal force loading by relating it to a body force density via the disk in order to increase strength (maximum stress) of circular rotating disk. Eventually, stress behavior of rotating disk is analyzed with considering geometric factors and material properties analytically. Finally, it is concluded that the mentioned factors affect on increasing and decreasing stress values of circular rotating disk under constant rotation.
Keywords: Centrifugal Acceleration, Equilibrium Equations, Rotating Disk.
